HarmoniXX frequency converters

Angewandte Physik & Elektronik (APE) has introduced the HarmoniXX product line - a series of frequency converters for mode-locked ultrafast lasers, particularly Ti:sapphire lasers, but also suitable for other wavelength ranges. It covers frequency doubling (SHG), tripling (THG), and  quadrupling (FHG), with a modularly structured system. User-friendliness and compactness had high priority in the design process.

With modest quick-release optics, the HarmoniXX devices are applicable for a wide pulse duration range from femtoseconds to several tens of picoseconds, and in particular suitable for extremely short pulses. The new products are optimised for highest conversion efficiency at various laser power levels as well as minimum pulse broadening.

A very special advantage is due to a single, non-split optical beam path. Unlike conventional triplers the new HarmoniXX tripler needs no separation and recombination of the interactive beams. Instead a special delay compensator is used whereby the search for the spatial overlap of the beams is omitted. This implements a very easy and quick adjustment and alignment.
